BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 265,030, dated September 26, 1882,

Application filed May 20, 1882. (No model.) i

To all whom it may concern:

Beit known that I, GILBERT DAVIS, a citizen of the United States, resident of Zanesville, in the county of Muskingum and State of Ohio, have invented a new and valuable Improvement in Brick-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a side view of my device. Fig. 2 is a front view of the same. Fig. 4 is a vertical sectional view. Fig. 5 is a sectional view of the mold broken 05.

This invention has relation to brick-ma chines; and it consists in the construction and novel arrangement of the open-bottom mold, the detachable base-board, and the pivoted end lifters, operating in connection with said mold and base-board.

The invention also consists in the combination, with the open-bottom mold and its baseboard, of the roller-bed and guideway below the press, the operating-levers, and the rock shafts in connection with the pressbeam and drag-bar, all as hereinafter set forth.

In the accompanying drawings, the letter A design ates the frame of the press, which is eon structed with a platform or table, B, at each end, and between these with roller-bearings G K indicates a horizontal drag-bar, which rests on the rear platform B, and is connected to the rock-shaft H by means of rods a, which are attached to its arms Land 1.

P indicates the press-follower, having a capbeam, M, which is connected by means of rods 1) to the arms c of the rock-shaft H, said arms Fig. 3 is a plan View, and

being arranged at right angles, or nearly so, with the lever L. When said lever is depressed the followerM is raised until the arms 0 pass the vertical, and then, the lever L resting on the ground, the follower is held in the raised position. i

Z indicates the mold, consisting of a rectangular frame, having several open-bottom matrices, d. The longitudinal wallse of this frame are extended, and between the extensions g are pivoted the broad swinging litters h, each of which is of greater depth than the distance from the pivotal bearin gs k to the lower edge of the frame.

Under the mold Z is the detachable baseboard V, which is long enough to extend under the lifters h, so that the latter can rest thereon by their lower edges in inclined position.

In operating the machine the mold upon its base-board is placed on the rear platform B, and the lever L is operated to move the dragbar K, whereby the mold and base-board are drawn squarely into the guide-recess F under the pressway. The charge of clay having been introduced, the lever L is actuated to depress the follower so that the mold is charged.

Then, the drag-bar having been returned to its original position, another mold is placed on the rear platform and pushed into the guide-recess F, thereby pushing the charged mold Z and its base-board out upon the front platform B, whence it is carried to the place of deposit for the newly-molded bricks. 'In this operation the mold Z is sanded; but not so the baseboard, as the clay is designed to stick somewhat tothe latter. When the place of deposit is reached the lifters it are worked upon the base-board by their lower edges to loosen the mold" from the bricks. Then the entire mold and base-board are turned over gently, the

board is cut loose from the bricks and mold with a wire, and, lastly, the mold, which has alreadybeen loosened by means of the lifters, is raised, leaving the bricks in position for dry- 111.

1 mold having compartments with bottoms adapted to pass into the same and assist by their weight in ejecting the brick is old. A mounted roller turning independently of the wheels on which it isborue and forming a guiding-carriage for the molds is also old, and a gage for adjusting the molds upon the carriage to be forced under the clod-cutter has been used prior to my invention, and I claim the open-bottom mold Z and its detachable base-board V, of the roller-bed and guideway F below the press, the operating-levers L L and rock-shafts H H, the press-beam M and drag-bar K, and the connections a b, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses. 4
